New Query Submission
Name: Ransomware Precursors
Author: ByteRay GmbH
Submission ID: 8c03f9ce-07ba-43f5-882a-22effd6cfa22
Description
Detects command patterns that ransomware operators execute immediately before encryption to prevent recovery: Volume Shadow Copy deletion (vssadmin, WMIC, PowerShell WMI/CIM), backup catalog destruction (wbadmin), Windows Recovery Environment tampering (bcdedit), USN journal deletion (fsutil), and mass shadow storage resizing. Each event is classified into a named hypothesis so analysts can triage by technique. These commands are rare in legitimate day-to-day operation and their appearance - especially several within a short window on the same host - is one of the strongest early-warning signals of an imminent ransomware detonation.
